Proof For Law of Refraction at a Plane Surface(By Huygens’ Wave Theory)

Chapter-10|Wave Optics|NCERT 12th Physics: Proof For Law of Refraction at a Plane Surface(By Huygens’ Wave Theory): Let after t time a ray comes from B to D and cover a distance V₁t. Now we will form a wavelet at point D. Now, after t time a wave comes from A to C with speed V₂  […]
